Occupational Hygiene Training Association (OHTA)

OHTA was established as an international training scheme and qualifications framework which provides free, high-quality, training materials in several languages and the infrastructure for low-cost training courses, as part of an internationally recognised programme of study. OHTA is a registered charity in the United Kingdom (Charity Registration Number: 1168722), and the US Chapter has obtained charitable status as a 501(c) (3) in the United States (Employer Identification Number 83-2036073).

What they do 

OHTA began as an international collaboration amongst dedicated occupational hygienists from several nations who wanted people from around the world to enjoy the benefits of a healthy working environment. The International Occupational Hygiene Association (IOHA) supports OHTA in its training activities.

To achieve their goals, they: 

• Develop, review and upgrade occupational hygiene training materials 
• Work with training providers and awarding bodies  
• Participate in educational conference sessions 
• Build partnerships with other like-minded organisations
